Her lawyer said she co-operated during a three-hour session but would not be drawn on details, adding that Mrs Ghosn is not expected to face further questioning.

Mrs Ghosn’s Lebanese passport was confiscated by Japanese police, but she travelled back into the country on Wednesday using her US passport.

The new investigation into Mr Ghosn involves allegations that he siphoned off millions of dollars from Nissan for personal use.

Reports in Japan claimed that $5m was funnelled to a British Virgin Islands-listed company to help fund the purchase a 120ft luxury yacht.

The automotive industry titan was first arrested in November over allegations that his income was under-reported - a crime under Japanese financial law.

He was held in custody for 108 days before being released under strict bail conditions last month, having been charged with shifting losses from personal investments to Nissan as well as under-reporting his pay.

However, the fresh claims that led to Mr Ghosn’s re-arrest are more serious and could lead to stiff penalties.

The latest arrest has interrupted treatment of Mr Ghosn’s chronic kidney failure, according to defence documents seen by Reuters.

His lawyers allege his arrest was designed to halt the defence's preparation and force a confession. They have called his latest detention and the impact it has had on his medical treatment “inhuman”.
